The hand movements were jerky too. Just like they were in the 1990s. I don't understand why we're still struggling with producing animation that isn't uncanny valley?
Most hand animations are done with keyframes, because mocapping hands is difficult. And with keyframes animation, much like modelling geometry traditionally vs photogrammetry, we can't produce the needed amount of details in animations for them to look real.
Moreover, we are extremely good at spotting something off with hands movement.
